- Limitations
- Ship-specific identity and service record, but NavSource is a volunteer compilation rather than a Navy registry. It contains no asbestos, survey, abatement, or hazmat information and does not establish final disposition beyond 'fate unknown.'

- Limitations
- This official Navy list confirms a dated unit-assignment/award period but does not describe the ship's material, asbestos, individual duties, or exposure conditions. The live NHHC URL returned 404 during direct verification; the NHHC search result and indexed page content were retained as the source lead.

- vessel_history
- Finding
- The ship page identifies PC-1133 as a PC-461-class patrol craft built by Defoe Shipbuilding at Bay City, Michigan, with the same laid-down, launch, and commissioning dates as NavSource. It lists two 1,440-bhp General Motors diesel engines, reduction gearing, and two shafts, and reproduces wartime operational narrative naming PC-1133 in Philippine operations.

- GAO report highlights and full-report PDF, Navy policy/use sections
- Finding type
- gov_survey
- Finding
- GAO reports that the Navy used asbestos in ships, that thermal insulation was the major shipboard use, and that asbestos also occurred in components such as clutches and electric cables. The report discusses Navy policies issued in 1975 and modified in 1979.

- Limitations
- Program-level evidence from Long Beach and Norfolk Naval Shipyards, not a survey of PC-1133. It supports only era context for a 1943 Navy vessel; it does not establish that any listed product was installed aboard this hull, the amount, condition, or any person's exposure.

[8]Batch-7647 source and litigation sweep; Firecrawl MCP and authenticated CourtListener helper logs [other_primary]
- Locator
- search_ledger rows sl-uss-pc-1133-pc1133-01 through -09
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, insulation/material list, abatement contract, hazmat disclosure, or qualifying asbestos-litigation record naming USS PC-1133 / PC-1133 was located in the sources searched. The CourtListener exact-name and hull-number searches were attempted through the authenticated helper, but the helper reported a fleet-wide daily quota exhaustion and a required wait of approximately 3.9 hours; therefore litigation is unresolved, not a negative result. Firecrawl likewise reported a keyless-MCP quota exhaustion.

- Limitations
- A located-record absence does not prove absence of asbestos aboard. The CourtListener and Firecrawl access failures are genuine research gaps. No exposure, causation, legal eligibility, or final disposition may be inferred from this negative finding. NARA deck logs and the USNA action-report folder remain archival leads.
